The business in Richards Street, on Phoenix Works Industrial Estate, is owned by his devastated father, who is also called Mohammed.

Kim Taylor said it had been an “absolute shock” to discover her stepson had burgled the embroidery firm, which she helps to run.

She said the cash had been her partner’s savings and the Asian gold jewellery had belonged to her stepdaughter Yasmeen Yousif, holding sentimental value.

Miss Taylor, aged 45, of Fullbrook, Walsall, said: “She was gutted. We still haven’t had it back.

“It has sentimental value. Her dad bought it her when she was in Pakistan when she was about 12 or 13.”

“It was an absolute shock and disappointment. We’re not speaking at the moment. We just wish he could have said sorry.”

Her stepson was sentenced beside Ryan Adams, aged 18, at Walsall Magistrates Court on Tuesday. Officers suspected an inside job as there were no signs of forced entry following the burglary on July 22.

Yousif and Adams were identified after CCTV was checked at a neighbouring property.

Yousif, of Bassett Road, Wednesbury, and Adams, of Bentley Lane, Birchills, both admitted burglary and were given 12-week detention sentences, suspended for 12 months, and told to carry out 120 hours unpaid work.
